ICE-COOLING APPARATUS.

PECIFICATION forming part ofLetters Patent No. 341,039, dated May 4, 1886.

Application iiled December S, 1884. Serial No. 149,717. (No model.)

To all whom it may concern:

Beit known that I, WENZEL J. MORAWETZ, of Milwaukee, in the county of Milwaukee and State of V'Visconsin, have invented certain new and useful Improvements in Ice-Cooling Apparatus; and I do hereby declare that the fol-v Its objects are, first, to maintain a dry at-V mosphere and a uniformly low temperature in the`cooling-chambers, and, second, saving of ice.

In the accompanying drawings, like letters refer to the same parts in al1 the iigures.

' Figure l represents a vertical cross-section of an ice-house to which my system is applied. Fig. 2 is a vertical section on an enlarged scale, and at right angles to that shown in- Fig. 1, of aportion of the flooring employed. Fig. 3 is a Vertical section of the ice-house shown in Fig 1, taken at right angles thereto, and cut-` ting one of the passages p longitudinally; and Fig. -1 is a horizontal section of the same, taken through openings fv o and g g, and the lower part of ice-chamber A and rooms D D.

The principle of my system consists, essentially, in inelosing a mass of ice in a chamber closed both at the top and sides by non-conducting walls, to prevent the escape of the cold air within andv the melting of the ice by the entrance of warm air from without, and in conducting the cold air produced by contact with the ice through openings in the walls next to the door into the bottom of coolingrooms adjoining, or through said openings into the hollow inner walls of said chamber, thence down through openings into and around the bottom of a cooling-room below, and, nally, of forcing the warm air in said cooling-rooms by the cold currents from said ice-chamber out through suitable ventilators leading from the tops of said cooling-rooms. The natural tendency of colder air to settle and of warmer air to rise is thus utilized.

ing 0r apparatus for carrying theforegoing principle into effect are susceptible of endless variation, according to varying circumstances of its application.

To illustrate my invention, I have selected the ice-house shown in the accompanying drawings with a single ice-chamber and a number of rooms adapted to be cooled therefrom.

A A is the ice-chamber, provided, in the usual manner, with a pitched or water-tight door, which has a ledge about its edges-and a drain pipe or passage, to conduct away the water produced by the melting ice.

,D D are cooling-rooms on each rside of the icechamber A and o'n the same iioor therewith. They communicate with the ice in said chamber A through openings g g at the bottom of the partition-walls, and are provided with ventilators d d, which lead from the top of said rooms.

The ice-chamber A is surrounded at the top and sides with walls s s, filled with some loose material-such as sawdust-to exclude the heat and retain the cold air within said chamber. It is lined on the sides with a tight partition or ceiling, r1', which extends from the topV of said chamber towithin abouttwo feet of the floor and incloses the air chamber or passages p p, which end'at the door when the but when it is desired to cool rooms below they are extended, as shown iu Figs. l and 3, to the lower iioor, and communicate through openings h. 7i and la k with the bottoms of cooling-rooms B and C C, which, like rooms D, are provided with ventilators b b c c, opening from the tops or ceilings thereof. Each of said cooling-rooms B, (l, and D are lined on the sides with tight walls or partitions r r, inclosing between themselves and the packed walls and partitions s s air chambers or passages which open into the bottom of said cooling-rooms, around the iioors thereof, and assist said packed walls and partitions s s in excluding the heat without and in retaining the cold within.

Theice-chamber A and cooling-rooms D D are provided with triple iioors, m n o, the up- The details and arrangement of the build-r side draft or cooling passages are alone used;

per two of which inclose the air-chambers n n and the lower two, a o, the air-chambers o o', which communicate through small openings into the circulatory passages pp. The foundation floor (not shown in detail) may be constructed in like manner. By this arrangement the floors are kept cool, and the warmer air in the tops of roomsC Cbelow is excluded and prevented from affecting the temperature of the rooms D D above.

The entire building next to the outer packed walls, s s, is surrounded by an air chamber or space a a, which assists said walls s s in excluding heat from the building and with the linings r r, inclosing air-spaces on the inside, tends to maintain a dry atmosphere within the several cooling-rooms and the ice-chamberA.

The various openings g g, h h, and la lc from the ice-chamber. A or the cold-air space or passages p p communicating therewith, are provided with doors g, h, and k', by means of which the cold-air current into any of said cooling-rooms B C D may be regulated or entirely shut off.

The several ventilators b c d are provided with registers or cut-offs e, which are operated by cords or wires f f, leading therefrom down through said ventilators into the various cooling-rooms.

The openings c o from the bottom of icechamber A are protected by narrow slats, as shown in Figs. l and 3, to prevent the ice from falling into the passages 1). The passages p p are preferably made to extend around the entire ice-chamber or coextensive with the partitions separating said icechamber fromv the cooling room or rooms, but are incidentally subdivided vertically by the studding used in the construction of the walls and partitions.

The operation of my improved ice-cooling system or apparatus may be described briefly as follows: rIhe chamber A is first compactly iilled with ice, as shown in Figs. l and 3, and all communication from without, except through the openings 'u o, is closed. To cool any of the rooms B C D, the doors opening from said ice-chamber A or the cold air-pas- Sages p into the same are opened, and the ventilators leading therefrom are opened until the warm air in said room is expelled by the cold current entering below from the ice-chamber A through openings o o, passages p p, and openings g, h, and lc. Vhen the temperature of the room has been sufficiently lowered, the ventilators are closed, and the coldair communication with the ice-chamber will maintain a uniform low temperature and a dry Vatmosphere in which matches may be kept for any length of time without detriment thereto. XVhenever the air in the ice-chamber A or in passages p p becomes cooler, and consequently heavier than the air in the lower part of the cooling room or rooms in communication therewith, it will settle, displacing the warmer and lighter air below, which nds its way by forming counter-currents through said openings and passages into said ice-chamber A, where it comes in contact with the ice and is cooled thereby. The warmer air collecting in the upper part of said cooling room or rooms is expelled, whenever it becomes necessary, through ventilators leading ont therefrom. By thus establishing communication between the lower and cooler parts of the several cooling-rooms and the lower part of the ice-chamber, and conducting the warm air from said cooling-rooms outside away from said ice-chamber, the place of the cold air passing from said ice-chamber to said several cooling-rooms is supplied by the cooler air found at the bottom of said cooling-rooms, and the unnecessary consumption of ice is prevented while its cooling effect is fully and economically utilized.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, in an ice-cooling system, of ice-chamber A, closed at the top and about the upper portion of the sides, and a cooling-room communicating with each other at or near the bottom' only of each through an opening, c g, and a ventilator leading out from the upper part of said cooling-room, substantially as and for the purposes set forth.

2. The combination, in an ice-cooling system, of the ice-chamber A, closed at the top and about the upper portion of the sides, a cooling-room below said ice-chamber, air-passage p, forming a communication between the lower portions only of said ice-chamber and cooling-room, and a ventilator' leading out from the upper part of said cooling-room, sub'- stantially as and for the purposes set forth.

3. The combination, in an ice-cooling system, of the ice-chamber A, having its ceiling and the upper part of its walls closed, and a cooling-room communicating with each other at or near the bottomonly of each through an opening laterally coextens'ive with the partition between them, and a ventilator leading out from the upper part of said cooling-room, substantially as and for the purposes set forth.

4. The combination, in au ice-cooling system, of the ice-chamber A, inclosed at the top and about the upper portion of the sides by non-conducting walls s s, lining r r, inclosing an air-space about said ice-chamber and forming passage p p, a triple oor inclosing airspaces n o', one of which communicates with said passage p, a cooling-room similarly inclosed and communicating at or about the bottom only with said ice-chamber at or near the bottom thereof only, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
